Design Of L3 MPLS/VPN Network

The global economy integration, multinational trans-regional telecommuting agencies increase sharply, the cooperation between enterprises and enterprises and customers are increasingly close relationship between customers and in different regions and between safety, high-speed, economic and effective data communication needs become increasingly urgent. This not only brings the complexity of the network, the network management and also safety problems. MPLS-with its efficiency and flexibility of virtual private network (VPN), become the expansion does not have previously networks of the function and the characteristic, a feasible scheme.China unicom as ip business provider, and its advantage lies in its ability to provide suitable for various kinds of enterprise application MPLS-solution VPN. MPLS-VPN solutions will greatly reduce customer cost in WAN and remote network connection fee, at the same time, will simplify network design and management, convenient network and access clients, also can protect the existing network investment. Anyhow,China unicom MPLS-VPN solution makes it all the more manageable, more economic.At present, China unicom to general backbone routers super core has opened MPLS exchange functions, all converge routing has MPLS/VPN ability. Now three layers of MPLS/VPN business framework and the related agreement has basic mature, and realized the certain scale commercial. Introduced the forming of Beijing current VPN network schemes, MPLS/MPLS/VPN business with.L3 of MPLS/VPN structure optimization and perfection of detail is currently China unicom problems need to be solved, such as VPN stratified structure, the multicast support, etc. How to apply the MPLS/VPN technology to provide more services.The standard technique of L2 MPLS/VPN especially VPLS is developing very fast and become a hot topic. But the interconnection performance between different L2 MPLS/VPN producers needs further investigation. Besides, we need to do further test on our current equipment to see if they could support L2 MPLS/VPN, based on the test result, we will standardize the key parameters of L2 MPLS/VPN service.
